Answer:

$\frac{5\sqrt{2} }{2}$

Step-by-step explanation:

$x: \text{opposite side of the angle of 45\º}$

$5: \text{hypotenuse of the right triangle}$

$\sin(\theta)=\frac{\text{opp}}{\text{hyp}} \Rightarrow \sin(45\º)=\frac{x}{5}$

$\text{Once }\sin(45\º)=\frac{\sqrt{2} }{2}$

$\frac{\sqrt{2} }{2} =\frac{x}{5} \Rightarrow 2x=5\sqrt{2} \Rightarrow x=\frac{5\sqrt{2} }{2}$

You can just remember that 5 is the diagonal of a square of side length x.

$5=x\sqrt{2} \Rightarrow x=\frac{5}{\sqrt{2} } \Rightarrow x=\frac{5}{\sqrt{2} } \cdot \frac{\sqrt{2} }{\sqrt{2} } = \frac{5\sqrt{2} }{2}$

Answer:

The volume of the triangular prism is $595\ units^{3}$

Step-by-step explanation:

we know that

The volume of the triangular prism is equal to

$V=BH$

where

B is the area of the base

H is the height of the prism

Find the area of the triangular base B

$B=(1/2)bh$

substitute the given values

$B=(1/2)(14)(17)=119\ units^{2}$

Find the volume

$V=(119)(5)=595\ units^{3}$
